今早打开IDEA启动项目，发现报了这个错误，这个是提示说，数据库需要换成6.0以上，那么就在pom.xml，文件里面把mysql改成6.0以上版本，如下:

<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<version>8.0.16</version>
		</dependency>

接着改了yml配置，把以前5.0的配置改成6.0以后的，如下:

5.0前版本的是:

driverClassName: com.mysql.jdbc.Driver

6.0后版本是:

 driverClassName: com.mysql.cj.jdbc.Driver
